The battery cover door to my D500 was lying inside my camera bag and seems to be extremely loose after reinstalling it (wobbly from side to side). Nikon has the part listed for sale on their website. Since I haven't used my D500 much - around 5k actuations - I'm wondering if I should order 2 or 3. The cost of one is only $5-$6. Just wondering if anyone else has run into this problem. That might help me decide how many doors to get.
